Vanquisher Class Corvette

The Vanquisher class corvette entered Terran Commonwealth Space Forces service in 2173CE.  Designed for patrol and intercept duty, the Vanquisher featured a HKD 300TW protium reactor with integral fusion drive rated for 30,000mt thrust at 250,000 isp.  Field-cut Ramirez-Cruz plasma afterburners provide up to 120,000mt thrust at 50,000 isp.  Fully loaded with 18,500mt MSMH fuel, the 30,000mt Vanquisher had over 2,340kps delta-V, though use of R-C afterburners often reduced this performance.  At cruising velocity, assume a non-refueling round trip, the Vanquisher could cross 1AU in 2.89 days, reaching Neptune orbit in less than 90 days.  Refueling at the destination doubled maximum cruising velocity.

The Vanquisher was one of the first production spacecraft to feature the innovative Crew Cage, an 18 meter freely rotating sphere containing all crew stations and quarters for the 20-36 personnel onboard.  The Crew Cage allowed constant “gravity” orientation while under thrust, landing on planetary surfaces, or skimming through atmospheres for refueling or braking. Artificial gravity under coast, was achieved by tumbling the vehicle end-over end, with the lower decks receive the most effective gravity.

The Vanquisher was designed for long deployments and was equipped for wilderness hydrogen refueling from atmospheres, liquid water or ice deposits.  Both purification and metastabilizing equipment was integral to the vessel, with two of the six main pods normally designated as refueling intakes.  The corvette was rated to 20g acceleration in any vector and 500 atmospheres pressure for gas giant and oceanic operations.

The twelve small and six large pods were designed for multi-function use and were easily interchangeable.  Forward and center pods normally contained communications, sensors or weaponry, including mass drivers, point defense lasers and missile launchers.  The large pods held fuel refining equipment, shuttlecraft and drone launchers.

While extremely stealthy in cruise mode, the Vanquisher provided a highly visible profile when under thrust or when operating its reactor at high power.

Of fifteen Vanquishers build before the Colonial War, seven defected to the Confederation and each side lost three corvettes during the fighting.  After the war, the TCSF procured an additional dozen vehicles, and the Colonial Confederation produced eight similar vehicles at Vesta Yards though four of these feature xenon-ion drives rather than MSMH fusion/plasma engines.

The Vanquisher class corvettes remained in service until replaced by more efficient patrol craft in the 2220s.
